8 bags
Which Grade?
One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water. http://www.planete-tp.com/en/article.php3?id_article=221
different density need different sand ,cement and water , cement and water is about 2:1 , details please visiti website:httP://www.foamed.com.cn
there are 108 20kg bags of concrete to 1 cu mtr. If your making your own mix using dry mix concrete requiring cement and water, and your making a mix ratio of 5:1, then you divide 108 by 6 = 18. therefore: 18x20kg bags of cement to 1800kgs of dry concrete mix.

96kg steel bar is use in 1m3 but also depend on diameter of bar
120 kg/m3

An Average of 2400 kg, with a ratio of 1:3 Cement and Sand
35.84 kg

Simply calculate volume of sand as you calculated volume of cement to be used, just don't multiply it with 1440, divide by 50 as in case of calculating cement.you will get your answer in m3 of sand.
